I know how to find the answers but, what is the difference? I know that a perimeter is all the sides added together but whats is an area exactly? (i know that you're suppose to multiply the length and the width to find it,thats not my question)My question is,what is it?

We usually relate numbers with three different units of measurement line, area and volume!
When you relate number of units in a 'line length' (centimetre units, inch units etc) it is regarded as "linear units"!
When you relate 'number of area-units' in a '2Dimensional figure that relate areas' (square centimetre units, square inch units etc) it is regarded as "area-units"!
When you relate 'number of volume units' in a '3 Dimensional object that relate volume' (cubic centimetre units, cubic inch units etc) it is regarded as "volume units"!
Technically all three units are different!
as...
10 centimetre length (for line), or
10 square centimetre (for area), or
10 cubic centimetre (for volume),
10 is "number part" in each of said measures and "units of measure" are added (that makes different senses)!
Coming back to your question, please note that your answers should categorically state "length, area or volume unit or any other concerned unit" of measurement! So, 10 centimetres, or square centimetres or cubic centimetres are different!

The perimeter is the total length of the outside edge of an object, and area is the total space covered. Imagine a square. If you measure the lengths of the sides and added them together you would get the perimeter--the length of the outside edge. Now fill that square. The space in between the lines that gets filled up is the area. Take the length and multiply it by the width and you have the area, or total space covered.

The perimeter is the measure of the outside, or border. The area is the measure of the entire inside. So if the a rectangle is 10 ft by 5 ft the perimeter is 30 ft. (10 times two sides plus 5 times two sides) The area is 50 (10 times 5)

Let us take an example of a square. Its sides are 4 each of a size a say. Its perimeter will then be 4a where as its area will be a^2 (a square). As the side increases in magnitude, the perimeter will increase proportionally ( 4 times the side) but the area will go up exponentially ( a square) and will thus increase much faster.
You can graph the perimeter and the area on y axis and the side of the square on x axis and see how the two graphs diverge. The perimeter graph will be a straight line.

The perimeter is only measuring the units of space that outline an object. The area is all of the units of space in the object. So like if I wanted to measure the perimeter of a fenced lot in feet, I would only want to measure the how long the fence is that surrounds the lot. If I wanted the area of the lot, I would multiply the bottom of the fence and the side of the fence.
So you can sort of say that the perimeter is the "fence" of an area.
Catch my drift?

The perimeter is a measure of length. More specifically, it's the length of a shape's border.
Area is a measure of area, not length. The area describes the amount of material needed to "cover" it. Length is 1-dimensional, area is 2-dimensional. For example, you can measure length in inches, but area needs to be in a unit such as square inches, as you're counting how many 1"x1" square tilings it takes to cover a given area.
To use a real-life analogy: if you wanted to put a fence around your yard, you would want to know your yard's perimeter. If you were covering your entire yard with those rolled-up beds of grass, you'd want to know the area.

In very simple terms:
Area means how much of plane surface a certain curve (usually closed) occupies & is measured in "square units" such as sq. inches or sq. cms. etc. So it has two dimensions: length and breadth.
Whereas, perimeter denotes the length of a closed curve and has one dimension only. It could be measured by travelling the distance around that closed curve once or cutting and straightening the same and finding the length so obtained.
The perimeter encloses the area.

The perimeter is the length of the boundary and the area is the space inside the boundary. So if it's a 10 cm square, the area inside is 100 sq.cm which means you have that much space inside the boundary

Area is that space which is bounded by sides, closed. The perimeter is simply the sides Think of your back yard, surrounded by a fence. Area is the ground enclosed by the fence, perimeter is the fence itself.

the area of any shape is a number that represents the amount of space covered by that space. the city of san francisco consists of about 49 square miles of land. so you can say that the city has an area of 49mi(squared). the city is almost shaped like a 7mi x 7mi square, so its perimeter is 28mi (4sides x 7miles each) and its area is 49mi(squared).
hope that helps! :)

Take a rectangle. The area is the space inside the rectangle and the permieter is the space around the rectangle
